Figure 31. Electron micrograph shows the presence of 

 PTA-stained few CyMV particles at droplet 

 edge (arrows) from the same tissue as in 

 Fig. 30. Bar = 200 nm. 



Figure 32. Electron micrograph shows the accumulation 

 of VaMo-stained CyMV and ORSV particles at 

 droplet edge (arrows) in high 

 concentration in an extract from a 

 Cymbidium leaf infected with both viruses. 

 Bar = 200 nm.
